On Board Diagnostic
System (OBD)
Malfunction Indicator Lamp (MIL)
The Malfunction Indicator Lamp (MIL) ¢..ifi in the
instrument cluster is part of the On-Board Diag-
nostic (OBD II) system .
The warning/indicator light illuminates when the
ignit ion is switched on and goes out after the en -
gine starts and the idle has stabilized . This indi-
cates that the MIL is working properly.
If the light does not go out after the engine is
started, or illuminates wh ile you are driving, a
28
malfunction may exist in the engine system. If
the light illuminates, the catalytic converter
could be damaged.
Continue driving
with reduced power (avoiding
sustained hig h speeds and/or rapid accelera-
tions) and have the condition corrected . Contact
your authorized Audi dea ler.
If t he light illuminates, t he electronic speed lim-
iter may also be ma lfunctioning. For more infor-
mation ¢
page 29, Electronic speed limiter.
An improperly closed fuel filler cap may also
cause the MIL light to illuminate

On-Boa rd Diagnostics mon itors the components
of your emission control system. Each monitored
component in your engine system has been as-
s igned a code . In case of a malfunct ion, the com-
pon ent will be identified and the fault stored as a
code in the contro l module memory.
The MIL light may also illum inat e if there is a
leak in the on -boa rd fuel vapor recovery system .
If the light illuminates after a refuelling, stop
the vehicle and make sure the fuel filler cap is
properly closed
